` Appicatitnfoctober 13, 1939,seramoasazsa `9 o1aims.f(o1. sil-"231)This invention relates" to a. cutter er cutting" t i elementordevice'for cutting cables principally, but also for cuttingfbars, rrodsand the like.

The primary object` of .the invention is to proi vide a cutter which4isrrelatively light in weight` f' `so `the same may be moved readilyfrom one location to another; whichiisprovided `with new and improvedmechanism; so as `toprngide great leverage to `eiectand insurerelatively easy-operation during` cutting; which ,is strong and durablein construction; which is easy andefcient jin operation; which is.`composed `of l. relatively few and simple parts get out of order. l i

Afurther important object of the invention is the provision of a cutter`vvhiehhas along pivotally mounted operating bar providing greatleverageso as to rotate abutting jaw in the form of a circularrotatively mounted ratchet operatand which is not likely to ing memberhaving peripheral ratchet teeth, the bar being operatedin` the cuttingystrokehby a cam on` an operating lever whereby a compound leverageprinciple is ,provided toinsure 1positive and easy cutting` Stillanother object whereby the movement of* the cutter towardcutn tingposition is prevented from moving in a reversedirection, a `condition`which is likely to exist because of the inherent lispringy. character``istics of the materialto lbecutysuch as cables or cable material. ,t ty Another object of the invention is to provide a cutter which has acompound-leverage priny,ciple of operation to produce positive cuttingwith the application ot a relatively small amount Hof force to operatealtrotatively mounted pawl operated ratchet cutter. t

t Numerous other objects and advantages will be apparent-throughouttheprogress of the following specication.

The cutter or cutting device herein shown for the purpose of`illustratingthe `invention comprises a base or `frame supportlgID, inthe ,form of a channelyhavinga ,bottom AIl);fronilsfand `rear t sides I2andil3,` respectively, and ends I4 land I5,

the end I4 being' closed and the end I5` being open `at or near itsupper end.` VThe sidesyl2 `and I3 terminate in upwardly extendingportions I6 to form supports or bearingsfora transverse shaft or axlelI1. Thisr axle fII` has "mounted thereon a circular element-,I8` whihis-preierably in the form ofa wheel;l The element or` wheel I8 may berotativelvmounted ori a nonrotatable axle I 'Iscr 4vthellwheel I8 maybefixed` to a revolubly mounted axle I1, j ust sefrotary4 n movement maybefgiven thereto. A n

`This element I8, yin the `form o fya wheel, gear, sprocket lor thelike,` is cut away-as indicated at I9, FigJLto provide a jaw 20,thejmaterialat one t l side-of the cut-away being, beveledfor. curved'to provide a suitablemovable)cutting edg'e2I. This cutting edge orcutting jaw 2|co-operates With a fixed or stationary cutting jaw or`cutting `edge 22.?Vformed'on fthe extending `or projecting edge `23 onthe front side member` I2 of the base support Ill. The cutting. jaws 2Iland.` 22 are adapted to co-operate with eachother soas `to i t cut acable, rod, bar, or the like" therebetween. The element IB is mounted`for rotativemovement which is. given thereto progressively by means ofan operating ratchet pawl `ZILadapted to engage ratchet teeth 25`formedon apart'of the periphery` i The ptawl `211 issubstantiallyr thesame width as the wheel I8, and it is pivotally mountedat 26` to alongitudinal barfor lever member 21 which.` is mounted for verticaloscil- `latory, movement on the shaft `or axle I1'. `The bar or levermember 21 comprises two side bars 2B and 2i)` whichengage the outsidesof the side members I2 and i3, respectively,` the side pieces 28 and 29being connected 'for apart of their lengths by a top piece orplate 3i).`,ihe V v I top [bar is thus guided by the side flanges 28 and 29 and isprevented from shifting laterally. The

free end of thelever `member'o1 j"b`a`r2l hasta roller 3l mountedthereon which isi adapted to engage an operating carri member32 on anoperating member or lever, arm 3 3.` The arm`3`3 is pivotally mounted ona .horizontal axis `314 carried by the sides"|2 and I3, an-d it' is inthe form of a socket toreceive a long handle 35 to provide greatleverage. When thej handle 35 is oscillated forwardly `(to the right,Fig.` 1), the cam 32 engaging the cam roller 3l will raise the free end(the end at they left, Figli) of, the lever bar 2l, and inasmuch as thepawl 24],is carried by this lever bar 2l and in engagement with theratchet teeth 25, the movement is transmitted to and against the cableso that the wheel I8 willVVV be prevented. from rebounding or rotatingin a counterclockwise direction. This means -may comprise a secondratchetpawl 35 which vis so positioned that when the wheel 'I3 isrotated at least one tooth 25, it will fall in between a vpair of teeth25, the'pawl 36 being so arranged as to hold the wheel I8 againstreverse'movement when the pawl 24 rides over the teeth on the returnstroke. The pawl 36 is mounted on a horizontal axis 31 which is suitablyIsupportedvby the sides I2 and I33 kof the framesupport Ill. After thecable,bar, rod or othermember is out the pawl 36 should b e released.Therefore, aprojection or finger 38 is xed or otherwise fastened to thepawl, there being an arcuate opening '39 formed in the side I2 to permitoperation-of the pawl.

The arcuate slot 39y is of a length suflicient to permit the pawl -toengagethe teeth 25 or to be swungon its ax-is 31out of engagement andsupported in out of the way position. In this latter position the ng-er38 will be in the extreme left hand edge of theV slot 39, Fig. 1. As thematerialto be cut rmaycause a binding action of the cutting jaws, forcemay be necessary to free or ease the wheel I8; andtherefore a socket 40is formed in an advantageous location in the periphery of the wheel intowhich a bar or other klever may lbe inserted to return the wheel to itsnormal position, Fig. 1. `To return the wheel I8 to its normal positionthe pawl 35 of course must rstj-be released( The releasing of the pawl3S may be accomplished by shifting the finger 38 fromthe right hand endof the slot 39 tothe left hand end ofthe slot.

'IfoY make the device ambulatory, so as to permit it to be movedlreadilyfrom one position to another, two or more wheels or rollers H areprovided. These rollers 4|y are mounted on suitable axles. 42 mounted inlugs or ears 43 fastened to the supporting base IIJ".l These lugs orears may be fastened to the base in any suitable manner, or they may beformed'integral therewith as shown. Also, to permit the device to behandled an end handle 44 and' side handles 45 may be provided. Thehandle 441is preferably similar to a wagontong'ue while the side handlesmay be in the form of rigid loops fastened to the sides I2 and I3 in anysuitable manner, such as by weldy ing.

The invention provides a rigid, durable cutter of simple design forcutting bars, rods and principally cable. The device can be movedreadily andveasily from one position to another and because ofitssimplcity can be economically manu* factured.' vBecause of thecompound lever action herein provided, very great'leverage can beobtained, theleverage being multiplied because of the particularassociation ofthe two levers which operate` the driving ratchet pawl.Moreover, the device consists of few and simple parts, and whiledesigned principally for cutting cables, it can be used successfully forcutting bars, rods and other articles of material; l
